GeForce GTX 480 vs Radeon RX 6500 XT

Intro

Compare all that to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has clocked the core frequency at 2200 MHz. The GDDR6 RAM runs at a frequency of 2250 MHz on this particular model. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce GTX 480		250 Watts
	Difference: 143 Watts (134%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 480 is 20% quicker than the Radeon RX 6500 XT overall, due to its greater bandwidth. (explain)

GeForce GTX 480		177408 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 29952 (20%)

Texel Rate

The Radeon RX 6500 XT should be a lot (approximately 235%) better at anisotropic filtering than the GeForce GTX 480. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 98800 (235%)

Pixel Rate

The Radeon RX 6500 XT is much (more or less 110%) better at full screen anti-aliasing than the GeForce GTX 480, and will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 480		33600 Mpixels/sec
	Difference: 36800 (110%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
